To all whom z' may concern.'

Be it known that LWILLMM H. Douanes, a citizen `of the United States,and resident of Belleville, in the county yof Essex and State of NewJersey, have invented a new and useful improvement in Clamps ,forWind-Shields, of which thefollowing is a specification. p

rThis invention relates to an improvement in clamps for wind-shields,,with the` object in view of providing a clamp which will be effective,cheap in construction and easy to manufacture.

Another object is to provide a device whereby the wind-shield may beremoved and replaced very readily without disturbing the clamp orstationary portionV of the supporting structure.

A practical embodiment of my invention is represented in theaccompanying drawings, in which- Figure 1 represents in detail portionsof the wind-shield and roof of an automobile with the device as appliedto one side thereof,

liig. 2 represents a transverse sectionV of the same taken in the planeof the line rifof F ig. l,

Fig. 3 represents a detail central longitudinal section on an enlargedscale, taken through the clamp and a portion of the wind-shield frame,

Fig. l represents a central section taken at right angles to F ig. 3,and

Fig. 5 represents a horizontal section taken in the plane of the lineB-B of Fig. 3.

The clamp consists of a stationary member and a swinging member. Thestationary member comprises a post 3, which may be secured between theusual support, not shown, and the roof 4, for supporting one side of thewindshield. This post is shown as provided with a head 6 formed integraltherewith and having` a cylindrical socket 7 therethrough forming anexteriorly unbroken wall.

A slot 8 leads from the socket 7 to a point 9, thereby forming walls 10,11, which are adapted to be drawn toward each other by means of a thumbscrew 12`passing freely through the wall 10 and having a screwthreadedengagement with the wall 11. The walls of the slot and socket form anunbroken continuation of the post.

A friction washer 13 may be placed between the wall 10 and the head ofthe thumb screw `l2.

The swinging member comprises a hub 1% adapted to rotate in .the spcketfr', which hub iS held therein by e plete l5 which @verle-PS the outerface of the head 6 and is secured to the hub by means of a screw bolt1G. The swinging member is further provided .with a channel 1'? cuttherethrough for the recep tion of the frame 18 of the wind-shield glass19. The frame 18 is secured in the channel 17 by means of ears 20carried by the frame and screws 21 having a threaded engagement with theswinging member. B v this means of securing the frame of the windshieldto the clamp, the shield may be readily removed and replaced withoutdisturbing the clamp or stationary portion of the supporting structure.

By turning the screw 12 inwardlv, the walls 10 and 11 will be drawntoward each other, which will contract the slot and socket and thusfirmly clamp the hub therein.

By turning the screw outwardly, the walls 10, 11, will be released andthe socket will be free to expand, thereby loosening the hub in thesocket, which allows the shield to be.

adjusted to any desired angle.

By forming the walls of the slot and socket in an unbroken continuationof the post, the walls of the socket will be contracted evenly andcaused to clamp the hub at all points around the same, as distinguishedfrom those clamps in which the walls are broken either at the socket orthe slot, where the clamping pressure will be uneven and therefore notso effective; the turning strain on the hub in one direction tending todiminish the gripping action of one jaw of the clamp and the turningstrain in thel other direction tending to diminish the gripping actionof the other jaw.

It will be understood that the normal condition of the socket and slotwill admit of a free movement of the hub in the socket, so that only aslight movement of the screw is necessary to tirmly clamp or release thehub.

It is evident that slight changes might be resorted to in the form,construction and arrangement of the several parts without departing fromthe spirit and scope of my invention; hence I do not wish to limitmyself strictly to the structure herein set forth, but

from one side'of the socket into the post, the

Walls ot' the socket and slot forming an unbroken continuation of thepost, a hub rotatable in said socket, and means interposed between thesocket and the end of the slot for uniformly contracting said socket andslot Jfor clamping thehub against movement. 1 2. In a wind-shield, apost havinga cylindrical socket and a longitudinal slot leading from oneside of the soeket into the post, the walls of the socket and slotforming' an unbroken continuation of the post, a hub rotatable in saidsocket, a framecarried 'by said hub, means for removably securing saidframe directly to the hub, and means interposed between the socket andthe end of the slot for uniformly contracting the Copes'of this patentmay be obtained for socket and slot for clamping the hub againstmovement. o i

3. In a Wind-shield, a post provided VWith a head having therein acylindrical socket and a slot leading therefrominto the post,

the Walls of the socket and Slot forming an unbroken continuation of thepost, a` hub rotatable in said socket, "a frame having'YY ears, meansfor removably securing said ears toV the hub, and means for contractingsaid slot andl socket for clamping the hub againstl movement.
